why do casinos allow insane betting limits on roulette but not blackjack

I’ve been messing around with some crypto casinos lately and it hit me how nuts the max bet numbers are for roulette compared to blackjack. Like, you can throw down house money on a single spin, way more than they’ll take for a single blackjack hand. I kind of get that there’s no real skill in roulette and they don’t care if you hammer red all night, but blackjack isn’t that much different if you’re not counting. Seems like a weird double standard.

I’m guessing maybe the house edge on roulette just makes them less nervous, but even so, if someone comes in with a six-figure stack, wouldn’t they be worried about a lucky streak either way? Or do they just figure the math always saves them in the long run for pure chance games? Wondering if anyone else has hit the ceiling on roulette bets and what happened. All I got was a polite “limit reached” message and a slow live chat agent.
